DOOR CHECK AND BUFFER.

Specification of Letters Patent.

Application filed April 19, 1910.

Patented Sept. 13, 1910. Serial No. 556,314.

To all whom 'it may concern:

Be it known that I, JOHN C. SIBISKI, a citizen of the United States ofAmerica, residing at Baltimore, in the city of Baltimore, State ofMaryland, have invented new i and useful Improvements in Door Checks andBufiers, of which the following is a specification.

This invention relates to door checks and buffers, the object of theinvention being to provide a device of this character consisting of aspring socket member designed for attachment to the wall and theprovision of a resilient head member for the door, the said head memberbeing adaptedfor engagement with the socket member to hold the door inan open position.

A still further object of the invention is to provide a resilient socketmember which can be constructed from a single length of sheet materialbent upon itself to form bracket arms, a main shank for theheadreceiving portion of the said socket member and to construct one ofthe bracket arms so as to brace the said shank portion.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a horizontal section through a door and through a portionof a wall showing the application of my improved door check thereto.-Fig. 2 is a do tail horizontal section through the check showing thehead member engaged with the socket member.

My improved door check consists of a socket member 1 and a head member2. The member 1 is formed from a single length of springy sheet materialwhich is bent upon itself so that its terminals form a shank 3 andbracket arms 1, one of the bracket arms being formed to provide a brace5 whose terminal is secured to the shank 3 by a rivet or equivalentfastening device 6. The material forming the socket member is doubled onitself at points outwardly of the shank 3 to form oppositely extendingjaws 7 whose outer ends are formed to provide heads 8 for a purpose tobe hereinafter described. The socket 9 is substantially of arrow formand it is closed partly by the heads 8. A strip of leather or suitableelastic material 10 is suitably secured to the jaws of the socket 9 ofthe member 1 as clearly shown, to form a bufler for a purpose to bepresently explained. The rivet 6 which secures the outer terminal of thebrace 5 to the shank 3 of the socket member serves to prevent separationof the jaws 7 when such jaws are moved away from each other. This rivetpreserves the elasticity of the socket member as will be understood.

The head member is formed from a single length of springy sheet materialwhich is bent on itself to form a substantially arrow head 11, a shank12 and the bracket arms 13. The folded portions of the metal forming theshank 12 are secured together by a rivet or equivalent fastening device14. The head 11 is formed to provide companion shoulders 15 whichoperate to engage similar shoulders 16 on the heads 8 of the socketmember. The bracket arms 1 of the socket member and the bracket arms 13of the head member are suitably apertured for the reception of suitablefastening devices which may be of a design adapted to be engaged withthe objects with which the said socket and head members are mountedupon.

The socket member 1 is designed for attachment to the wall as shown inFig. 1 of the drawing and the head member is secured to the door in aposition where it can be effectively engaged in the socket 9 of themember 1 as will be understood. The socket member is formed to provide aflared entrance passage '17 for the reception of the head 11. of themember .2, the design of the head ll of such member being such that itsinclined or beveled side walls engage the surfaces 18 of the heads 8 soas to expand the heads or move them away from each other until the head11 is positioned in the socket 9, whereupon, the heads 8 will be closedupon the head 11 of the member 2 to hold the same confined.

I claim:

1. A device of the class described comprising a socket member formedfrom a single length of spring-y sheet material bent on itself toprovide bracket arms, a shank and a pair of spring jaws, one of theterminals of such metal being formed to provide a brace having its outerend secured to the said shank, and a head member designed for engagementwith the said socket member.

2. In a door check, the combination with a socket member formed from asingle length of springy sheet material bent upon itself to formcompanion spring jaw members, each jaw member being formed at its outerend to provide a head portion, the said member being formed to provide ashank and a signed to be engaged by the heads of the said pair ofbracket arms and one of said bracket spring jaws. 10 arms being formedto provide a brace arm In testimony whereof I afiix my signature whichis connected with and secured to the in presence of two witnesses,
